Indoor LED Module

p4 indoor led module

What is the difference between P3 and P4 LED? How can we distinguish them？ (1) Price: Generally speaking, the prices of P3 LED module will be higher than that of P4 LED module as P3 LED module has higher resolution and clearer visual performance. (2) Resolution: When it comes to LED displays, the difference between P3 and P4 lies in the number of points per area. P3 has a higher number of pixels per square meter, with around 111,111 pixels compared to P4’s 62,500. The smaller...

320*160mm P1.25 Indoor LED Display Module

A P1.25 LED module is an ultra-high-definition indoor display panel with a 1.25mm pixel pitch. It is widely used for crystal-clear, close-up viewing in command centers, TV studios, and corporate boardrooms. It delivers 4K resolutions on smaller screens and seamless visual performance.

192*192mm P3 SMD Indoor P3 LED Display Module

The P3 indoor LED module is a high-resolution LED display panel with a 3mm pixel pitch. Although small in size, it offers 4096 RGB LEDs, which are distributed in a matrix of 64 by 64. This module combines red, blue, and green to provide full-color text, images, and video for a variety of indoor LED video walls. In addition, it is easy to use and allows you to create any size LED display and place it in various environments. It focuses on visual performance and delivers an immersive visual feast.

What Is Indoor LED Display Module?

An indoor LED module is the fundamental building block of a modern indoor LED video wall. It is a self-contained panel consisting of tiny LED lights, a driving circuit (Driver IC), and a printed circuit board (PCB). When tiled together, these modules create seamless, high-resolution screens for indoor environments.

How it Works: Multiple modules are snapped together into larger frames called cabinets or panels, which are then linked to a central controller to project images and videos.

Key Characteristics

Pixel Pitch (Resolution)

Indoor modules use a measurement called pixel pitch (the distance between adjacent LED pixels). Indoor viewing requires high resolution, so standard modules use small pixel pitches like P1.2, P1.5, P1.8, P2, P2.5, P3, P3.076, P3.91, P4.81, P4, to P5, etc. (representing distances of 1.2 mm to 5 mm).

LED Technology

They predominantly use SMD (Surface Mounted Device) technology, which packages multiple colors into a single diode. This allows for wider viewing angles, crisper details, and better color mixing at close distances.

Brightness

Compared to outdoor models, indoor LED modules have lower brightness requirements. They are designed to prevent eye strain and deliver vibrant visuals without reflecting glare in ambient indoor light.

Environment

Indoor modules are not weatherproof. They lack heavy waterproofing, robust UV protection, or thick protective casings.
